Macrophages import cystine through their x c ??? transporter, reduce it to cysteine and then export the cysteine through their ASC neutral amino acid transporter.

MDSCs express the cystine transporter but lack cystathionase and the ASC neutral amino acid transporter
Therefore, macrophages, DCs, and MDSCs can import cystine; however, unlike macrophages and DCs, MDSCs are unable to export cysteine.
MDSC sequester cystine and prevent T cells from obtaining cysteine which is important for Tcell activation.
